An enhancement method for low-illumination image comprises the following steps: (1) inputting images; dividing the images f(x, y) with the sizes of M*N into rectangular areas which are not mutually overlapped in different sizes of m*n; (2) setting the size of a Wallis filter sliding ...
现在的研究比较常见的方法有Histogram Equalization(直方图均衡化),通过统计像素值出现的频率,计算累计分布,然后调整直方图的分布,使其更加均匀,从而增强整个图像的对比度。Retinex-based methods方法是将图像分解为illumination(照明:光线对物体的照射)和reflection(反射:物体表面反射回来的光),算法独立的调整这两个部分。 ...
An improved low-illumination image enhancement algorithm was proposed to solve the problems that the overall intensity of low-illumination color image is low, the color in the enhanced image is easy to be distorted, and some enhanced image details are drowned in the pixels with low gray value....
Nighttime low illumination image enhancement is highly desired for outdoor computer vision applications. However, few works have been studied towards this goal. In addition, the low illumination enhancement problem becomes very challenging when the depth

文章标题:Low-light image enhancement with joint illumination and noise data distribution transformation 联合光照和噪声数据分布变换的微光图像增强 期刊:The Visual Computer 1.简介&摘要 低光照图像增强主要存在两个问题,即低对比度和噪声,针对低光照图像特点与问题,增强方法主要分两种:第一种为只增强对比度(即只...
论文阅读笔记--Joint High Dynamic Range Imaging and Super-Resolution from a Single Image Retinex-based的图像分解 ,只有映射分量由CNN实现,而其他分量(illumination)以常规方式处理。在训练CNN时,我们设计了适当的损失函数,以提高所得图像的自然质量。实验表明,我们的算法优于基于CNN的SR和HDRI的级联实现. 但是,对...
